I hear you. I sold a 2018 Topps Update Acuna #250 SSP (white jersey batting) for about $225. I could've held out, but I'm happy that a super collector on this site bought it from me.

If you can find it, it sells for more than 10 times that. I wonder if that price will go down since the Braves didn't really 'need' him to win the WS and he has been so prone to injuries. Same with Tatis. Franco seems like a legit kid with a good head on his shoulders and so far appears grateful for his shot in the majors. I see a lot more of Mike Trout in Wander Franco than Tatis or Acuna.
And, yes, it was confusing in 2019 when there were 3 different Wander Francos in the Minors at the same time. I remember trying to connect to the correct one when I uploaded the Midwest League Propsect set.
